Cindy runs a company that designs and prints gift cards for a department store. Quality controls is very important, and Cindy must determine that the cards are being printed properly. For every 6,000 batches of 100 cards that are printed, she examines every 100th batch to make sure the logo is aligned and the magnetic strip works. Identify the population and the sample.
The population in this scenario would be ALL the batches of gift cards that are printed by the company. The sample would be the batches of gift cards that Cindy examines, which would be every 100th batch out of the 6,000 batches printed.
In this scenario, the population refers to all the batches of gift cards that are being printed by Cindy's company. It includes every single batch, regardless of the number.
The sample, on the other hand, is a subset of the population that Cindy selects to examine for quality control purposes. In this case, she examines every 100th batch out of the 6,000 batches of 100 cards that are printed. Therefore, the sample consists of these selected 60 batches of 100 cards each.
population is 6,000 batches
sample is batch examined
